I have purchased many of these traffic cones for my car wash business over the years and these have been the ones that have stood up to the most abuse and been repeatedly run over! I have 42 of these cones in total and each one is still working just as well as the day I received it. The coating on the outside helps to clean the skittles, wipe lightly with a damp cloth and you're done! Would recommend to anyone looking for traffic cones of this height!
